制定配电系统分时电价:支持系统灵活性,实现低成本电气化

Comments Off on 制定配电系统分时电价:支持系统灵活性,实现低成本电气化

在世界范围,分时电价机制正在逐渐普及。时至今日,大部分国家的分时电价都是根据使用时间,将发电相关成本分摊到不同的时间段中,同时在各个时间平均分摊电网相关成本。本文的主题是将分时电价机制的概念延展到配电系统定价中。

最近,一些国家和地区已经开始着手处理这一课题。在此,我们关注到了丹麦电力市场正在发生的变化,丹麦在将分时电价用于配电系统定价机制中已先行一步,有些经验可圈可点,我们在此梳理了一些相关经验,也许对世界各地的政策制定者有所启发。

Levelling the playing field: Aligning heating energy taxes and levies in Europe with climate goals

Comments Off on Levelling the playing field: Aligning heating energy taxes and levies in Europe with climate goals

Taxing energy in line with its environmental harm aligns the prices facing consumers with policy objectives. Energy taxes and levies encourage energy efficiency and raise revenues for governments, which can then dedicate them to energy transition projects. Not all energy sources are equal, however, when it comes to their environmental-damage costs. Adding taxes and levies disproportionately to electricity encourages the continuation of an emissions-intensive status quo and discourages investments in key decarbonisation technologies, such as heat pumps. This paper shines a light on the imbalance in energy taxation across almost all European markets and makes the case for reform.

The authors explain the current structure of energy taxes and levies in five key European countries where reform would be beneficial: Italy, Spain, the United Kingdom, Belgium and Germany. All five countries overtax electricity — in three cases by more than 200% — and undertax oil and fossil gas while not taxing wood use at all. Only in Italy is the tax rate on heating oil close to the value of the environmental costs caused by its use.

The European Commission’s proposals in the Fit for 55 Package would go a long way towards addressing the taxation issue. But these proposals would need to be implemented and there’s no guarantee they’ll survive the upcoming negotiation process. Member States wishing to align their tax and levy policies with their climate targets can act now to begin the process of rebalancing.

The authors detail four approaches to rebalance energy taxes and levies, drawing on examples from around the continent.

  • Option 1: Lower tax on electricity for heating
  • Option 2: Environmental taxation
  • Options 3 and 4: Shift levies to public budget or fossil fuels

Power System Blueprint

Comments Off on Power System Blueprint

Accomplishing climate neutrality by 2050 requires a zero-emissions power sector by the mid-2030s. Securing a decarbonized power system early will unlock pathways for the whole economy. One of the biggest challenges to accomplishing this ambitious goal is time—we have a need for speed if we want to meet decarbonization goals by 2035.  

This is why RAP has created the Power System Blueprint, an interactive website that allows visitors to view different options for decarbonizing Europe’s power system. The Blueprint lays out how to design the regulatory context to achieve a clean, reliable, equitable and affordable European power system by 2035. RAP pulled together the latest insights for supporting regulators, NGO’s, governments and anyone interested in the decarbonization pursuit. 

The Blueprint is designed as a schematic of regulatory solutions linked to six important central principles. In the suite of regulatory solutions (also known as factsheets),you will find comprehensive information, the most important regulatory steps and further reading. 

The decarbonization of the power sector can be done by 2035 but will require a rapid and systemic rethink of the existing European power system regulatory landscape. Within the Power System Blueprint website, you’ll find solutions to some of the some of the largest tasks we face working within this tight timeframe.

国际视野:对创建“全国统一电力市场”的下一步工作建议

Comments Off on 国际视野:对创建“全国统一电力市场”的下一步工作建议

近日,国家发展改革委、国家能源局发布了《关于加快建设全国统一电力市场体系的指导意见》 (发改体改〔2022〕118)。该文件为电力市场改革又向前迈出了重要一步,比如,该政策中制定了总体目标,要求在2025年前,国家市场与省(区、市)/区域市场协同运行,电力中长期、现货、辅助服务市场一体化设计、联合运营。同时,还提出优化电力市场总体设计”,“建设全国统一的电力市场体系,统一交易规则和技术标准等关于电力市场建设的要求。 

基于国际相关经验,以及对中国电力市场的了解,本文分别从以下五点提出落实该政策可考虑实施的建议,仅供参考: 

  • 以统一的算法优化区域调度的区域现货市场,是清洁能源转型的重要组成部分 
  • 中长期合同利用金融手段比物理手段更灵活、更利于可再生能源发电并网 
  • 电力现货市场的一个关键功能是在调度决策中反映不同资源的真实边际成本 
  • 输电定价不应成为统一区域市场和调度的壁垒 
  • 支持发电机容量成本回收的措施应谨慎加以限制。
